Patented '.lune V1,6,` 1931 d MILES nfsronlvnor :Pi f A kApplication led yMay '16,'k -My inventionrelates, broadly speaking, to

improvements sheaves', but has particularl reference to they sheave type line guide for draw works as Vdisclosed in my Patent No. 1,570,116,"datedJanuarylS), 1926. f VAn outstandingA objectof this inventionis to provide inla sheave type'line guide' means for effectively lubricatingy theijline passing through the guide/and at the same `timelnbrieating the bars uponjwhichfthe-sheaves'are slidably and 'rotatably mounted.y

` A further object resides in the provision of a novel sectional sheave having means for; efficiently and economically supplying lubri=` cant to both the axis andperipher-and thisl -without weakening the construction or'otherwisee'fl'ectingloss of etlic'iency.`=' 1 ,d Another! object otthejinvention fis to furnish a sectional sheave incorporating a f lnbric'ant chamber'interinediate thej'aXis and periphery andfincluding novelwick means for conveying lubricant to both the 'axi'sandu periphery.' i l Y ff n f The invention also resides'in-certainnovel` 'features of construction,combination 1 and "arrangement ofthe various-parts and in certain modes" of operation,.-all of which 'will bey readily nndersto'od y and appreciated'- by those skilled in the art upon reference tothe accompanying drawings connection with Vthefollowing 'detailed'description.`-" f1 1 rlhe drawings illustrate the now lpreferred embodiment Vof the Y invention,"- `tlie same, however, beingcapable of othermechanical expressions within the spinit and :scopeof'the subjectmatterclainied hereinafter,xV p E In thecliav/Kings,V l p." i Fignre lV isa side elevational view-partly 40 broken "and illustrating a 'sheave i'ncorpojatg-Y A Y ingv my invention ;l

wo series, offboltsf8,-9, respectively,` l 'which'areradially spaced, as shown.f

'Ihe periphery olf-eachr section 5 yis beveled inwardly, asiat 5a, toward: its 'innerfface to provide the `cable #receiving y groove 510-i't 95 being alsonoted that the ,sheaveisprovided f with' an annular,lubricantjchamber Aformed ybyOppvQSed Vcircumferi-i;ntial grooves 1l in the rinner face ofeach' sectiom Afsubstantially hereinabove4 re- ,S5

sections 5 extending, as shown, through the annular lubricant chamber 11, 11.

The outer periphery of the wick 12 extends to a point ilush with the bottom of the line groove and in fact forms the intermediate bottom portion thereof, so that the line in said groove will come into direct stressing contact with the wick 12.

Lubricant is supplied to the annular chamber formed by y.opposed circumferential grooves 11,-therey being provided, as shown, a boss 13 extending from the side of one of the sections 5, this boss havinga duct 13a communicating through the section 5, as

shown. The outer end of the duct 13a is adapted to be closed by a cover or closure 14.

Particular attention is directed to the bosses 8b, 9b, protruding from the inner face of each section and through which the respective bolts 8, 9 extend. The bosses 8b serve to tightly compress the wick 12 at cir- .cumferentlally spaced points adjacent the periphery of the sheave, while the adjacent or surrounding base portion of such bosses 8b serve to compress the wick also, but of course to a lesser degree. The base portions of the vbosses 8b aredesignated as 80. The effect of the bosses 8b, 8c is, therefore, to compress the wick at circumferentially spaced points adjacent the periphery of the sheaves and also to crowd the wick laterally intermediate such bosses so that the same willmaintain contact with the opposed surfaces of the section 5 between the bosses 8b, 80.k The bosses 8b, 8c therefore tend to facilitate the economical supply of klubricant to the line groove 10 of the sheaves and serve as aV check upon the capillary action of the wick 12l at points therebetween. j

The inner series of bosses 9b surrounding the hub 6 at the inner facesof the sections 5 are adapted to `be brought into bearing contact by the bolts extending therethrough, thus, providing a very rigid assembly of the sedaions 5 at the site of the hub 6, 6. The surrounding ledges or kbase portions 9c of the vbosses 9b, serve to compress the wick after the 'fashion of the ledges or base portions 8c mentioned in connection with the bosses 8b. It is tobe understood that the wick 12 will be cut out to provide recesses 12a for the reception of bosses 9?),-the ledgeor base portions 9 6 bearing against the surface of the wick immediately adjacent each boss 9b in attempting to crowd the portions of the wick between the bosses so as to spread the wick laterallyat such points for contact with the surface of the sections between ledges 9c. g

Y Figure 5 clearl 'shows thatfbetween the jledges 9c there is 1n effect provided passages 9d for the passage of lubricant tothe shafts 7 whereby the same will be effectively lubricated at all times, but without however allowing a Wasteof the lubricant,-which is to say an excessive supply thereof to shafts 7. f
